Ever think to yourself, “Wouldn’t it be cool if we had a navigation system like they had in video games? Well, MIT is working on a really interesting project called ‘Guiding Light’, which is an  indoor positioning system app that works as a GPS for indoor locations. Check out the video below!

Based on pico projectors and a combination of sensors the device is able to detect your location within a building, along with the direction that you are facing. Once your location is obtained, the device projects a small arrow in the direction that you should walk to reach your destination.If you wanted to find a specific store in the mall, this would be great.
